What does it mean when the tire pressure light is flashing?

Tire pressure light flashing generally indicates that the tire pressure is either too low or too high, at which point tire inspection and pressure adjustment are necessary. Hazards of low tire pressure: Increased friction coefficient with the road surface, leading to higher fuel consumption; Causes the steering wheel to feel heavy and may lead to veering, which are factors detrimental to driving safety; Increases the movement of various parts of the tire, causing abnormal heating due to excessive rolling; Reduces the functionality of the cord and rubber, leading to delamination or cord breakage, and excessive friction with the rim causing damage to the bead area and abnormal wear; The friction between the tire and the ground increases exponentially, causing a sharp rise in tire temperature, softening the tire, and drastically reducing its strength. High-speed driving may result in a tire blowout; Increases tire body deformation, making the tire side prone to cracking, while generating flexing motion that leads to excessive heat, accelerating rubber aging, fatigue of the cord layer, cord breakage, and also increases the tire's contact area with the ground, accelerating shoulder wear.
My car has experienced the situation where the tire pressure light flashes before, which is usually the Tire Pressure Monitoring System (TPMS) alerting you to a potential issue. The most common reason is that one of the tires has too low pressure, such as being significantly below the manufacturer's recommended value, prompting the system to automatically activate the warning mode, with flashing indicating immediate attention is needed. However, it could also be a sensor issue, such as a dead sensor battery or signal interruption, especially if the light flashes briefly after starting the vehicle. Another possibility is a system malfunction, like poor module reception or data loss due to vehicle jolts. I recommend stopping as soon as possible to check all tires with a tire pressure gauge to confirm if the pressure is normal; if everything seems fine, it's best to visit a repair shop to inspect the sensors or the entire system. Don't ignore this small light—it helps prevent tire blowouts and makes driving safer. Developing a habit of checking tire pressure once a month, such as when the car is cold in the morning, can prevent similar issues from arising.
As someone who frequently drives long distances, my tire pressure warning light has flashed a few times, indicating an issue with your tires that needs immediate attention. The most common cause is low tire pressure, such as when temperature changes cause the pressure to drop or when there's a minor leak that hasn't been noticed. However, it could also be due to a loose or aging sensor sending false signals, especially on bumpy roads. If the light only flashes a few times at startup, it might just be the system performing a normal self-check, but continuous flashing is a cause for concern. My approach is to immediately find a safe place to pull over and use a tire pressure gauge to check each tire individually—don't rely solely on visual inspection. If the pressure is low, inflate the tires to the standard value, usually listed on the label inside the door frame. If everything seems fine, the sensor might be faulty, and you should contact a professional repair shop as soon as possible. Remember, a flashing tire pressure warning light is not a minor issue; ignoring it can increase fuel consumption or lead to accidents. Regular maintenance, such as quarterly checks, can save you a lot of trouble.
My old car sometimes has the tire pressure warning light flashing, which is basically a warning that there's an issue with the tire pressure system. Most of the time, it's because the tire pressure is too low, falling below the threshold and triggering the alarm. However, it could also be a sensor malfunction, such as being dirty or having poor signal. When I encounter this, I simply check the tire pressure first. If that's not the issue, then I consider taking it to the shop. Don't delay, as it's unsafe to drive and also wastes fuel.
